The MINERALLAC FBO6 is an electrical box support designed to secure outlet boxes in ceiling and wall installations where a dedicated structural backer is not present. Known under the BLACKCLAW product line, this adjustable fan brace-style support mounts directly inside standard ceiling or wall openings and holds junction or outlet boxes firmly in place. It is a standard component in residential and light commercial electrical rough-in and retrofit work, typically installed by licensed electricians or experienced electrical contractors. Weighing 0.24 pounds, it is a lightweight but rigid solution for box mounting applications.
The FBO6 is suited for use in ceiling fan, light fixture, and general electrical box installations where direct framing attachment is not practical. It is commonly used in retrofit scenarios such as replacing an existing light fixture with a ceiling fan, or adding an outlet box in a finished ceiling without tearing out drywall. The support spans between joists or framing members to provide a solid, code-compliant mounting point for the electrical box.
Designed as an OEM-style replacement and general-use support for standard residential and light commercial electrical outlet or junction boxes in ceiling and wall applications.
Installation is typically performed by a licensed electrician in accordance with NEC requirements for box support and securing. Always shut off power to the circuit at the breaker panel before handling any electrical box or wiring. The support bar should be fully engaged with the framing or structural surface before attaching the electrical box. Do not exceed the box and fixture weight ratings marked on the installed box or support device.
